Kevin Rangel, check the contrast settings first. Display contrast

The brightness and contrast of the display can depend on room lighting, battery freshness, and viewing angle.

To adjust the contrast:

1. Press and release the "2nd" key.

2. Press "+" (to darken the screen) or "-" (to lighten the screen).

Hope this helps, good luck.

The basic problem with the 36X Pro LCD is that it has blue numbers against a green LCD background unlike a normal TI-30X IIS whose LCD has black numbers on a green LCD background.

/Huge difference in contrast!
